90% accuracy in detecting melanoma: New non-invasive method

A team of researchers proposed a non-invasive method for detection of melanoma. A patented computer-aided diagnostic system developed by scientists proved to be more than 90% accurate in detecting malignancy in diagnostic images of skin lesions acquired from 100 patients.

How allergens trigger itching: Finding points to new targets for allergy drug development

A key step in the immune system's response to allergens has been uncovered. Researchers have shown that a neuropeptide called Substance P is released by certain neurons in the skin when they detect allergens, and that this substance is essential in the development of allergen-induced immune responses. This research could lead to the development of new and better methods to treat and prevent allergies.

Langerhans cells are up to the job, they just need a chance

Researchers found that Langerhans cells (LCs) play a crucial role in mucocutaneous acute guest-versus-host disease (aGVHD). Their experiments in mice showed that when the LCs of a recipient were depleted, the formation of mucocutaneous lesions was enhanced because the infiltration of CD8+ T cells was inhibited. Their findings have significant implications for improving blood stem cell transplantation treatments and clinical outcomes for patients.

Diagnosing Parkinson's disease with skin samples could lead to earlier detection

New research shows a simple skin test can accurately identify Parkinson's disease, which could lead to earlier detection of the disease and better outcomes for patients. Currently, Parkinson's disease is diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy. The researchers conducted a blinded study of 50 skin samples using an assay originally designed to detect mad cow disease.

Technique to recover lost single-cell RNA-sequencing information

Researchers have greatly boosted the amount of information that can be obtained using Seq-Well, a technique for rapidly sequencing RNA from single cells. This advance should enable scientists to learn more about the critical genes expressed in each cell, and to discover subtle differences between healthy and diseased cells for designing new preventions and cures.

New insight on mole growth could aid development of skin cancer treatments

Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study.

Discovery enables adult skin to regenerate like a newborn's

A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps.

DNA damage caused by migrating light energy

Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers have demonstrated that DNA damage may also occur far away from the point of incidence of the radiation. They produced an artificially modeled DNA sequence in new architecture and detected DNA damage at a distance of 30 DNA building blocks.
